Grea!, Never admit a mistake or existence of a problem, even if it's not your creation and you have little knowledge of facts.

What could possibly be wrong with a profile? Something like a super secret double no-fly list or something similar. Twice, even the check-in agents have had trouble printing all my BP's. Today, neither the check-in agent, nor the nice Skyclub ladies could print my LAX-SYD BP. It's obviously not my computer.

Similar things have happened some of my domestic flights. Consequently, I have not had a glitch free trip this year. Either I couldn't check-in, if I could check-in, it wouldn;t print any boarding card(s), on multiple occasions even Delta agents were unable to print the BPs, until I have flown a few segments. Once I was checked in for one segment of the return trip. LAst night, when I got to the print BP popint, it would say, we apologise for not being able to print your BP (Right, Delta apologises for my compiUer being bad! ). You are checked in. Please go back to the check-in page to print your boarding passes. I went back to the initial check-in page. It made me go tjhrogh the steps I had already gone through, with the samew result and the same advice to go back to the check-in page. I had expected that DL would say "You are already checked in, please print your BP's n ow". But NO. DL claimed I was checked in but it still made me put in my Passport, DoB and other relevant information again and again.
But Of course, The respondent above and DL know my computer is bad.
Meanwhile people in the tech support must be lying that they have many unresolved bugs.
